Theory, until proven factual, is fiction. Law is factual. The problem with many areas of science is that the scientists are accepting non-fact over fact. Thus, science itself is following a form of devolution, just like all of human-kind.
So you don't know what quantum mechanics is, I guess. Well, that is ok, read and learn...
When you look into it in depth, you will find that quantum mechanics is simply complex probability.
When you get down to the basics of it, you will find that science theory is often composed of science facts that are combined in a new way. Thus, a theory can have facts in it. But the way that they are combined is the theory part in the standard meaning of the word "theory." Just because some facts are combined to form something that somebody thinks might be true, doesn't necessarily mean that the thing absolutely is true.
If science theory were not theory in the general sense of the word, it would be called fact or law rather than theory.
In science theory is subjected to peer review, repeatable, observable tests that validate this theory. When someone talks about theory in science you can be sure this theory has been validated, dissected apart by hundreds if not thousands of scientists. Each scientist wants to make a name for himself by invalidating any of the existing theories. That is how science works my friend.
When a theory is validated, if it has not become fact or law, it is simply validated as a theory. There are many ideas that have been proposed as theories, but peer reviewed that they could not stand up as theory.
Quantum mechanics does not agree with Newtonian laws.
Again, this is because quantum this or that is only complex probability. Being probability means that it does not necesarily exist factually.
How can you know that Newtonian mechanics does not fully describe the interactions between objects. Well, look at trajectory of Mercury around the Sun. Space-time fabric is bend by the Sun gravitational pull, and Mercury does not follow the trajectory calculated by using Newton's laws. Space time fabric is bend and Mercury follows it.
Nobody knows for a fact that space/time fabric bends, or even that there is a space/time fabric. Space/time fabric is based on theory. Theory is not fact or law. At best, it is a possibility.
Regarding the orbit of a planet around the sun, popular cosmology has not taken into account the electric plasmas that flow throughout the universe. Electrical force is way stronger than gravitational force. This has been proven by science, and is considered to be standard fact... that electrical force is much stronger than gravitational force. See

BTW, what you consider a 'law' today, might be invalidated tomorrow, just like any 'theory'.
I completely agree. However, for something to be declared a scientific law, it must be overwhelmingly validated in some great way. That's why Newtonian laws are still laws, and most of the great theories are still theories.
If we followed your logic of 'God must have done it" we would certainly devolve over time.
This is exactly what is happening. Here's how you can know it is happening.
Science wants to believe in theories which are not law, rather than accept law until it is proven to be less than law.
You don't cross a busy street, because you believe in all the physical laws regarding what will happen to you when you are hit by the traffic. Why won't you accept the laws of physics, but would rather trade them for things that are not laws?
PS. Just don't call quantum mechanics God, please.
Quantum Mechanics is quite the opposite of God. God deals in reality. QM is simply probability.
